Hox proteins are evolutionarily conserved homeodomain containing transcription factors that specify segment identities along the anteroposterior axis of almost all bilaterian animals. They exert their morphogenetic role by transcriptionally regulating a large battery of downstream target genes. Therefore the dissection of transcriptional networks regulated by Hox proteins is an essential step towards a mechanistic understanding of how these transcription factors coordinate multiple developmental and morphogenetic processes. High-throughput techniques allowing whole-transcriptome mRNA expression profiling are powerful tools for the genome-wide identification of Hox downstream target genes in a variety of experimental settings. Here, we describe how to quantitatively identify Hox downstream genes in Drosophila embryos by performing a Hox transcriptome analysis using microarrays.
